What is a reversible reaction?A reversible reaction is a reaction that proceeds both forward and backward at the same time.
In other words, it is a reaction in which as the reactants react to form products, the products simultaneously react to form reactants.
Thus, looking at the original forward reaction:

If the oxide contains 22.24 % O by mass, what is the identity of the metal?
Express your answer as a chemical symbol.
Answers
The oxide contains 22.24% O by mass, so the identity of the metal as a chemical symbol is lead (Pb).
What is metal?A substance with high electrical conductivity, luster, and malleability, which readily loses electrons to form positive ions (cations) are called metals.
Mass percentage of oxygen in the oxide, i.e.,
ω(O) divided by 100 ω(O)
=22.24% ÷ 100%.
Mass percentage of oxygen in the oxide, i.e .ω(O) = 0.2224
Now the mass percentage of oxygen in the oxide multiplied by 100 ten we get the mass of oxygen in the oxide. If we take 100 grams of compound:
1) m(O) = ω(O) * 100 g.
Mass of oxygen in the oxide, i.e. m(O) = 0.2224 * 100 g.
Mass of oxygen in the oxide. i.e., m(O) =22.24g
Amount of oxygen, i.e.,
n(O) = mass of oxygen in the oxide ÷ molar mass of oxygen.
n(O) = m(O) ÷ M(O) amount of oxygen
n(O) = 22.24g ÷ 16 g/mol,
amount of oxygen i.e. n(O) = 1.39 mol
Mass of metal in the oxide, i.e., m(M) = 100 g - 22.24 g.
Mass of metal in the oxide i.e., m(M) = 77.76g
Now we to find the molar mass of metal oxide,
Molar mass of the metal :
= mass of metal in the oxide ÷ amount of oxygen(M)
= m(M) ÷ n(M). M(M)
= 77.76 g ÷ 1.39 mol.
Molar mass of the metal will be 5.94 g/mol.
Therefore, The identity of the metal is lead (Pb).

Phase Transition:
The three main states of matter are Solid, Liquid, and gas. A phase transition occurs from one state of matter to another when energy is supplied or cut.When energy is supplied to the molecules, solid converts to liquid, and liquid converts to gas. Then, the energy increases the speed of the molecules, the density decreases and phase transition takes place.On the other hand, when the supply of energy is stopped from the molecules, the gas turns to liquid, and liquid converts to solid. Both the temperature and pressure are in the same phase.Therefore, there will be no phase transition in the sample. Hence, it is a true statement.

In ironmaking, iron metal can be separated from iron ore (Fe2O3) by heating the ore in a blast furnace in the presence of coke, which is a form of carbon: 2 Fe2O3(s) + 3 C(s) → 4 Fe(s) + 3 CO2(g) If 1000 kg of iron ore and 120 kg of coke are heated in a blast furnace, determine the limiting reactant, the theoretical yield of iron metal, and the theoretical yield of carbon dioxide.
Answers
The limiting reactant is iron ore, the theoretical yield of iron metal is 701.344 kg, and the theoretical yield of carbon dioxide is 413.292 kg.
Stoichiometric problemFrom the equation of the reaction:
[tex]2 Fe_2O_3(s) + 3 C(s) --- > 4 Fe(s) + 3 CO_2(g)[/tex]
The mole ratio of iron ore to carbon is 2:3.
Mole of 1000 kg of iron ore = 1000000/159.69
= 6,262 moles
Mole of 120 kg carbon = 120000/12
= 10,000 moles
Thus, it appears that the carbon is in excess while the iron ore is limited in availability.
The mole ratio of the iron ore and the iron produced is 1:2. Thus, the equivalent number of moles of iron produced will be:
6,262 x 2 = 12,524 moles
Mass of 12,524 moles of iron = 12,524 x 56
= 701,344 g or 701.344 kg
Thus, the theoretical yield of iron is 701.344 kg.
The mole ratio of the iron ore and the carbon dioxide produced is 2:3. The equivalent mole of carbon dioxide produced will be:
6,262 x 3/2 = 9,393 moles
Mass of 9,393 moles carbon dioxide = 9,393 x 44
= 413,292 or 413.292 kg
The theoretical yield of carbon dioxide is, therefore, 413.292 kg.

a ⇒ b
c ⇒ x
So: x= (c×b) ÷a
Distance in miles in this caseIn this case, you can apply the following rule of three: If the car for 1 gallon of gasoline gets 56 miles, for 15.5 gallons of gasoline it gets how many miles?
1 gallon ⇒ 56 miles
15.5 gallons ⇒ x
